in Spain, No. 566/16,044, granted August 28, 1894 and I do herebydeclare that the followin g is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to use the same.

This invention has relation to a certain new and useful improvement forattaching the fillets on the flats of the revolving cards; and

the object thereof is to provide an improved apparatus for mounting thefillets on the flats;

and with this and other objects in view the ter more fully described inthe accompanying specification and illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the stretchingdevice. Fig. 2 is an end elevation of Fig. 1 from the left. Fig. 3 is aplan View of the head supporting the adjustable block. Fig. 4is across-section of the head. Fig. 5 is a detail of one of theclampingblocks. Fig. 5 is an end view of the clamp-block. Fig. 5 is asectional view on the line 'y 'y of Fig. 5. Fig. 6 Figs. 7 and 8 showfurther details of the head. Fig. 9 is a longitudinal section of thestretching device. Fig. 10 is a section on line E F of Fig. 1, lookingin the direction of the arrow. Figs. 11, 12, and 13 are plan views ofthe steel strips of holders with variouslyformed tongues. Fig. 14 is asection on line G H of Fig. 11. Fig. 15 shows a cross-section of a flatwhen stretched. Fig. 15 shows the flat when the steel strips or holdershave been placed in position on the side edges of the fillet, and Fig.16 is a plan view of the flat.

The flat a, is first of all placed in position in a trough-likebed-plate 11 between a traveling or adjustable and a stationary block b19*,

mounted at the left and right ends of the frame of the machine,respectively, the adjustable block I) being worked to and fro by meansofa hand-wheel c at the end of a screw 0, fixed in said block, while thestationary block is firmly fastened to the frame. The block b is thenworked forward, so as to engage with and pin the flat a vise-likebetween it and the stationary block. The flat being now immovable, thefillet d is laid onto same.

The fillets are very often made from one to three millimeters narrowerand five to twentyfive millimeters shorter than the flat in order toallow for stretching. When this'is the case, I stretch the fillet inboth longitudinal and lateral directions, taking the longitudinaldirection first in the way I will now describe.

I provide the'blocks b 5 holding the flat in position, with catches e 6of which 6 turns or balances on a pin or pivot e and is formed with anoblique surface 6 on its under left portion, while its right side tapersand is formed into a hook e Against the said oblique under surface e isinclined a pressinglever f, fixed by means of a pin f in a guideframe fin such way that pressure on said lever forces the left end of the catch6 upward and consequently the right end or hook e downward, causing thelatter to engage with and pass through the fillet, so as to hold thesame fast. The guide-frame f mentioned is firmly screwed or otherwisefastened to the frame of the machine. The function of the second catch eis to enable the fillet to be pressed against the flat and at the sametime to stretch said fillet lengthwise. Said catch a is pivoted on thepin 6 and is provided on its left side with a hook e for holding a cord6 pin 6 for guiding said cord. A prolongation or projecting part of theframe I) is provided A pulley e is also fastened on the said withnotches f and serves as a guide for a double lever f pivoted at f andheld in position by a spring J. On the upper half of the lever f is ahook f Fig. 9, which is connected by a rope 6 running over the pulleyc", with the hook e of the catch. On the lever f a pawl f is alsoarranged. In order to lay the fillet on the flat, the lever f,, ispulled by hand toward the left in the direction of the arrow, whereuponthe spring f becomes stretched and the pawl f falls simultaneously intoone of the notches f the lever f being thus held in a fixed position.The fillet is now pushed under the hook e and the pawl f released,whereupon, in consequence of the contraction of the spring f, the leverf is drawn back into its original position, thereby stretching the corda and pressing the hook against the fillet, which is thus stretchedlongitudinally in the direction of the arrows 1 and 2.

Having stretched the fillet lengthwise, as above, I stretch the samelaterally as follows: I first of all perforate the fillet along itsright side, by means of any suitable tool, in such way that theperforations correspond to the holes in the flat underneath. I then layon the fillet one of the steel holders or strips 9, as shown in Figs. 11to 14, in such way that the tongues g of the same pass through thefillet, through the hole in the fiat, and project underneath said fiat,the side edge of said steel meanwhile projecting somewhat over the sideedge of the fillet, as shown in Fig. 15. In order that this position ofthe steel strip 9 may be sufficient to firmly hold the fillet, thetongues ,g' of said strip are made broader above than the diameter ofthe holes in the flat. After fastening the fillet on the right side ofthe flat, as described, I stretch the former laterally by means of thefollowing arrangement: Above the bed on which the flat rests is acover-like pressing and stretching device, Figs. 1 and 10. Said deviceconsists of a gun-metal bar W, on which is fastened, by means of screws72 a steel plate h, having a notched lower edge or teeth It. Each end ofthe metal bar 77, is pivoted onto a swivel-pin h, fitted in the frame,and by means of which the pressing and stretching contrivance can beraised to enable the flat a, with its fillet cl, to be placed inposition on the bed-plate b. The bar 77. has at each end an arm 77.provided with notches 72, and passing through levers 7L Said levers hturning on pivots h, are provided with triangular pieces k Fig. 10,which engage with the notches h". A lever 11, carrying a movable weight2', is pivoted onto the frame at 71 and when the stretching device israised is supported by its arm 1 resting against the frame of themachine.

While the fiat Ct is being laid in the bedplate I) and while the filletdis being laid on the same, stretched lengthwise and secured on itsright side by means of a steel strip g,

the pressing and stretching device is kept in a raised position, restingon arm 11.

After the flat- CL has been placed in position and the fillet preparedin the way described it is requisite to stretch the latter in case it benarrower than the fiat. For this purpose the pressing and stretchingdevice is lowered, which causes the steel plate to engage with the leftloose edges or side of the fillet d, Fig. 10, and by means of the teeth7t of said plate the fillet is held fast. The lever 71 is then pushedonto the arm h, which passes through the slot it said arm being presseddownward by the weight 2', and the steel plate h thus caused to pressthe fillet firmly against the fiat. As is seen in Fig. 10, the metal bar77, is supported in slides v on guides o of the frame, said bar beingmovable to and fro by turning the screw-spindle 41 working in the femalescrew '0 by means of a hand-wheel o. On turning the hand-wheel i; themetal bar 77. is moved laterally to the left and with it the steel plateh, holding fast by means of its teeth 72 the fillet d. The latter beingthus stretched, it is perforated on the left side in such way that itsperforations exactly correspond to the holes in the fiat a, and is thenfastened by means of a steel strip g, as in the case of the right side,being now in the posi tion shown in Fig. 15. It will be remembered thatthe upper parts of the tongues g of the steel strips 9 are broader thanthe diameter of the holes in the fiat, and that the fillet is firmlysecured without the tongues 9 being bent back after said tongues havebeen firmly pressed into position. When said tongues are pressed back,therefore, there can be no danger of the fillet getting jerked out ofposition, the more so when the sides of the steel strips are also bentover at right angles, as shown in Fig. 15, since the fillet is not onlyfirmly held from underneath, but also at the sides, which is animportant advantage in that the steel strips lie in one and the samelevel with the side face of the fiat. For carrying out these operationsI provide a head K, containing pressing-blocks, as shown in Figs. 3, 4,6, 7, and 8. The under part of said head serves as a matrix for thescrew spindle or shaft L, which is driven by power transmitted throughconical change-wheels in the usual way. When the work is begun, the headK is on the right side of the machine. Said head consists of the lowerpart K, in which are arranged the supports M M, which slide in adovetailed groove or bed by means of a screw N, Fig. t, which works intoa fixed matrix N. The supports M M are moved to and fro by means of ahand-wheel N Into the head K are pushed slide-arms O, which carry smallscrew-studs O, on which rest rollers 0 Through the action of a spiralspring 0 the arms 0 are constantly drawn inward. The consequence of thisis that the rollers O deflect the projecting portions of the tongue gwhen the head K is moved to the left by turning the screw spindle orshaft L. On the supports M M are arranged the supports P P, which can beadjusted in vertical direction by means of screws P P, and to whichsupports are screwed clamping-blocks P P Figs. 4. and 6. Theseclamping-blocks taper toward the ends, in order to deflect to a rightangle the projecting edges of the steel strips 9 on turning thescrew-shaft L and moving the head K to the left simultaneously with thebending back or deflecting of the projecting portions of the tongues g,Fig. 15. For the sake of clearness a clamping-block is shown in detailin Figs. 5 5 and 5, in which Fig. 5 is a front elevation, Fig. 5 anelevation of the side of the block which engages with and bends theprojecting edges of the strip, and Fig. 5 is a section on line y 'y ofFig. 5. From Fig. 5 it will be seen that the faces 4" r of the blocksform an angle with each other, which is ninety degrees, for the purposeof bending downward the projecting sides of the strips.
